PANY OF NEW YORK, N. Y., A CORPORATION OF NEW Be it known that I, HERMAN G. Ko'rrnn, a citizen of the United States, and resident of Englewood, Bergencount New Jersey, have madea certain new an useful Invention Relatin to Vacuum Cleaning Apparatus, of which the following is a specification, taken in connection with the accomdrawings.

T is lnvention relates to vacuum cleaning apparatus and relates especiallyto vacuum c eaning apparatus actuated by the weight of the operator.

In the accompanying drawings showing in a somewhat diagrammatic manner an illustrative embodiment of this'invention, Figure 1 is a .longitudinalvertical section taken substantially along the. line 1'1 of Fig. .2. Fig. 2 is a topview. Fig. 3 is an end, elevation and Fig. 4 is a erspective view illustratmg the operation of the apparatus.

The ap aratus may comprise a movable f wood or other suitable material provided, if desired, with suitable rolls or casters so as to enable it to bemo'ved more members ma thelowerheads 20, secured to the-base readily. The sidei rolls 29 ma as indicated be mounted adjacent either si e of the base so as to take the weight transmitted by.

the brackets 30., 31 an additional. bearing if desired be provided in the form 0 the end rolls 28 mounted adjacent either end of the base. A suitable support ma be movably mounted in any .desir 'way on the movable base so as to o erate suitable pumping or vacuum devices y the relative movement of these parts. The support 3-may be mounted on the base as by the brackets 30 31 carrying the pivot pins 32 which may engage the side braces 27 secured to the su ort 3 or other suitable portions thereof. n this way the support 1s oscillatingly" mounted with respect to the base so that when du lex suction devices are employed one may direction. .The vacuumdevlces may be in the form oflbellowsfjpumpslcomprisingsuitable heads, sueh' hs'f25,26fmounted on the support and bas'e to which-the flexible bellows members 22, 28,- maybe secured as by suitable binding membersl24fi. If desired, however,

may have the bellows members otherwise "secured to them by.;gluing,vtacking or other means. The head 20 may be provided with asuitable discharge openin 17 which also extends through the base an with a suitable discharge valve 19- of resilient character or otherwise yieldingly held in the closedposition'indicated. The suction opening 12 may be closed by a similar suction', valve 36 mounted upon thehead 20. This suctionopening asindicated in Fig.1, communicates with a suitable suction passage 14; formed in the base and communicating with the suction opening 11 cooperatin with the separating receiver 1 and with t e suction opening 13 of the duplex vacuumdevice. T 70 e suction passage may as indicated be in the form-of 'a suitable slot formed in the Patented 1 -I v.1'5, 1910. A

base member and having its lower side closed by the strip 15 mounted therein. The suction valve 37 mounted on t he 'head 21 controls the suction opening 13 and this head and the cooperating which may be provided with the dischar opening 16 controlled by the resilient y mounted discharge valve 18. I

Any suitable separating receiver, such as 1,0 sheet metal or other material may be mounted on the base by the screws or other ing 33 in the support This receiver may be provided with a suitable cover 4 removablyheld thereto by the win other fastening members whic bring the cover down into. engagementwith the packing 8 in a suitable so as to make a tight oint. Suitable screens 9, '10 ofjcloth or other material may be removably mountedw'ithin thereceiver 1n any oove in the receiver v desired-way so as to interc'e t and collect;-

the hose connectionfi, the end of which engages the nipple 6 i'n' the cover.v This hose orfvacuum connection 5 ma connect, as inthe'dust and other material rawn through 1 dicated in Figs. 3 and 4, wit asuitable nozzle handle or suction tube34 so as to'exert the idesir suction actionon the suction nozzle The "apparatus may be operated in desired way-by the weight of the operator wo ma stand upon t port an faslthe suction nozzle 35 is moved e oscillating supalternately back and forth over the floor a rocking motion is naturally imparted to the support which actuates the suction devices and creates a powerful suction action in the connected receiver and suction nozzle. The operator can of course by exerting suflicicnt force on the nozzle handle push the apparatus along the floor to the desired extent while it is being operated, so that it is possible without interrupting the operation of theapparatus to clean a considerable floor area by the weight of the operator which may of course be partly sustained by the nozzle handle or otherwise.

tion pumps mounted at either end of said base to be operated by the movement of said support in either direction by the weight of an operator, said suction pumps each comprising heads secured to said support and base, a flexible bellows member connected to said heads, and valves,"there being a suction passage formed by providing a slot in said base, a cover strip mounted in said base cooperating with said slot to close said suction passage, a separatin receiver mounted on said base adjacent tie central portion thereof and projecting through an aperture in said support and connected with said suction passage by a suction opening in said base, screens removably mounted in said receiver, a cover removably mounted on said receiver and having a flexible suction connection secured thereto, a suction nozzle and nozzle handle of such length as to be engaged by an operator uponsaid support, said nozzle being operatively connected with said flexible suction connection.
